A pillow cover is a protective and decorative fabric case designed to encase a pillow. It helps keep the pillow clean and can be easily removed for washing. Pillow covers come in various materials, such as cotton, linen, and polyester, and are available in different sizes to fit standard, queen, or king pillows. In addition to their practical use, pillow covers can enhance the aesthetic of a room. They are available in numerous colors, patterns, and designs, allowing individuals to match them with their bedding, decor, or personal style. This versatility makes pillow covers a popular choice for home decor.
